1 Source of materials

An amount of 0.2672 g 8-carboxymethoxy-quinoline-2-carboxylic acid (1.0 mmol), 0.1341 g 1H-pyrazolo[3,4-b]pyridin-3-amine (1.0 mmol),0.040 g NaOH (2.0 mmol) and 0.1244 g nickel(II) acetate tetrahydrate (0.5 mmol) solids were added to the 30 ml ethanol-water (v:v = 2:1) mixed solution with stirring. The solution turned immediately clarified. The mixture was stirred for 4.5 h at 68 °C. After the reaction was stopped and cooled to room temperature, the solution was filtered into a small beaker. The colourless block crystals of the title Ni(II) complex were received in four weeks.

2 Experimental details

The hydrogen atoms were positioned geometrically (C–H = 0.93–0.97 Å, O–H = 0.65–0.85 Å). Their U iso values were set to 1.2U eq or 1.5U eq of the parent atoms.

3 Comment

The 8–carboxymethoxyquinoline-2-carboxylate ligand could form mononuclear compounds or coordination polymer with metal ions, since it has multiple coordination atoms (O,O,N,O). The crystal structures of Mn(II), Co(II), Ni(II), and Cu(II) complexes constructed by 8-carboxymethoxyquinoline-2-carboxylate have been reported, and they show the different coordination structures [5, 6]. Interestingly, despite the same starting material and synthesis conditions, it can form structurally different complexes with Ni(II) ions. Our research group has also been studying the synthesis and structure of related metal complexes [7], [8], [9], [10]. In this work, we synthesized and structurally resolved a Ni(II) complex different from that reported in ref. [6] with 8-carboxymethoxy-quinoline-2-carboxylic acid, 1H-pyrazolo[3,4-b]pyridin-3-amine, NaOH and nickel(II) acetate tetrahydrate. The molecular structure of Ni(II) complex is shown in the Figure. The Ni(II) complex is a mononuclear compound and made up of one Ni(II) ion, one 8-carboxymethoxy-quinoline-2-carboxylate ligand, three coordinated water molecules, and one uncoordinated water molecule. The central Ni(II) ion is six-coordinated in an octahedral environment with two carboxylic O atoms (O2 and O5) and one N atom (N1) from one 8-carboxymethoxy-quinoline-2-carboxylate ligand, and three O atoms (O6, O7 and O8) from three coordinating water molecules. The bond angle of O6–Ni1–O8 is 174.27(10)°, indicating that O6 and O8 atoms occupy the axial positions, and O2, O5, O7, N1 atoms forms the equatorial plane. The bond lengths of Ni–O are 2.058(2)–2.245(2) Å, and that of Ni–N is 2.287(2) Å. Furthermore, Ni(II) complex forms 3D supramolecular structure through intermolecular hydrogen bonding and p–p stacking interactions. In ref. [6], the carboxylic O atoms and ether O atom of 8-carboxymethoxy-quinoline-2-carboxylate ligand are coordinated with Ni(II) ion, however, the ether O atom does not take part in coordination in this work. It is worth mentioning that, although 1H-pyrazolo[3,4-b]pyridin-3-amine is not involved in forming the Ni(II) complex, it seems to have an effect on the coordination mode of the Ni(II) ion.
